radar test Flashcards
radar information is derived from both ______and ______ radar systems.
primary and secondary
In what class of airspace may secondary radar be used as the sole display?
Class A
If primary radar is temporarily unusable or out of service secondary radar service alone may be used as long as what condition exist?
pilot is advised and the condition is temporary. also describe location
what is the correct phraseology to request the cessation of Electronic Attack Activity?
- stop stream, stop burst in area
2. stop buzzer
Are merging target procedures necessary for aircraft established in holding?
no
To which 3 categories of aircraft must merging target be applied?
- aircraft at 10,000 feet and above
- Turbojet aircraft regardless of altitude
- Presidential aircraft regardless of altitude
Are controllers required to issue traffic information to aircraft that are separated by more than the appropriate vertical separation minima?
no
After an aircraft is informed “radar contact” when will it discontinue reporting ?
discontinue reporting over compulsory reporting points
Radar service is automatically terminated and the aircraft needs not to be advised of termination when:
- ______
- _____
- aircraft cancels IFR flight plan except when in class b and class c airspace, TRSA or where base radar is provided
- Aircraft conducting instrument, visual or contact approach has landed or instructed to change advisory frequency.
Discrete beacon codes are normally are normally assigned by the ______
ARTCC computer
Unless otherwise specified in a directive, LOA, or coordinated at the time of handoff when may you request an aircraft to change its beacon code?
only when the aircraft enter your area of responsibility
What code will be used in military aircraft operating on VR Routes?
4000
What code will be used by an aircraft in emergency status and not radar identified?
7700
What code should be used by an aircraft experiencing radio failure?
7600
What two VFR code assignments may be used in lieu of 1200 for aircraft in firefighting and Search and Rescue operations?
1255 for firefighting
1277 SAR missions
What code is reserved for use by pressure suit flights and aircraft operations above FL600?
4400-4465 or “4400 series”
What code may be used by an aircraft in a hijack situation?
7500
What factors must be considered when approving or disapproving a request to operate in Class A airspace with a failed transponder?
Disapprove or withdraw previously issued approval in Class A airspace with failure of transponder due to traffic conditions or other operational factors. Its controllers discretion
What pilot report is necessary for an altitude readout to be considered valid?
Mode C altitude readout
What is the proper phraseology to change the code of an aircraft that is squawking an incorrect code?
Reset transponder , Squawk 1234 (correct code)
or Altimeter, verify altitude +/- 300 feet
What is the proper phraseology for requesting an aircraft to turn off the altitude part of its transponder?
Stop altitude squawk, altitude differs by (# of feet)
What are the three methods of primary radar identification?
- observing a departing aircraft target within 1 mile of the take off runway end at airports with a operating control tower,
- observing a target who position with respect to a fix or visual reporting point corresponds with a direct position point received from an aircraft and the observed track is consistent with the reported heading or route of flight
- observing a target make an identifying turn or turn of 30 degrees or more
What are the four methods of secondary (beacon) radar identification?
- Request the aircraft to activate the “IDENT” feature of the transponder and then observe the identification display
- Request the aircraft to change to a specific discrete or non-discrete code and then observe the target or code display change
- Request the a/c to change transponder to “standby”
- Enroute. An aircraft may be considered identified when the full data block is automatically associated with the beacon target symbol of an a/c that is squawking a discrete code assigned by the computer.
What is the necessary action when any doubt exists as to the radar identification of an aircraft?
re-identify aircraft or terminate radar service
When must an aircraft be informed of its position when radar identification is established?
Inform an aircraft of its position whenever radar identification is established by means of identifying turns or by any of the beacon identification methods outline
When must an aircraft be informed of radar contact? 2 answers
- initial radar identification in the ATC system is established
- subsequent to loss of radar contact or terminating radar service, radar identification is reestablished
